To all ywhom t may concern Be it known that I, JOHN F. OCo'NNoR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Yokes, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings,'forming a part of this' specification.

rIhisinvent'ion relates to improvements 1n yokes.`trl

The object ofthe invention is to pro-vide "a novel type' of horizontal yoke which may be readily attached toA and detached from a standard draw bar, whether the latter is provided with a. coupler-key slot or not.

In the drawing forming a part of this specification, Figure l is a side elevation of a draw bar and yoke showing my improvement in connection therewith. Fig. 2 is a horizontal sectional view taken substantially on 'the line 2`2 of Fig. l. Fig. 3 is a pcrspective view of the head improved yoke. And Fig. 4 isa perspective view of the yoke proper.

In said drawing, 10 denotes a standard draw bar, the butt of which is provided with the usual upper and lower shoulders ll-ll. The improved yoke, considered as an entirety, consists of a yoke proper A and a connecting head B. The yoke proper, as shown, is of the horizontal type and has horizontal arms 12,*12 connected by rear portion 13, and each of said arms 12 is provided at its forward end with an enlarge ment forming rear inner shoulder 14, front shoulder l5 and front side shoulder 16, all of said shoulders 14, l5 and 16 extending vertically, as clearly appears from Figs. 2 and 4. The head B, which is of U-shape, comprises a rear vertical wall or follower portion 17, upper and lower forwardly eX- said walls 18 dicated at 19, to correspond to the shape and size of theenlargements at the forward ends of each of the arms of the yoke proper. In addition to therecesses above described which form vertical shoulders coperating vwith the vertical shoulders of the yoke proper, each of the forwardly extended walls 1.8 is provided on its inner face with a transversely extending shoulder 29, the

operate with the shoulders 11-11 VAof the draw bar butt.

The draw bar and head B are assembled by vrelative transverse movement, that is,

the draw bar butt 'can be slipped laterally or sidewise between the arms or the Walls l8`18 of the head soA that the shoulders 11 of thedraw bar vbutt engage behind the shoulders 20-20 of the head.v vWith vthis connection, it is apparent that the draw bar and head B will move in unison in both buil and draft. assembled with by relative vertical movement between the head and yoke proper, that is, by lifting the yoke proper vertically so that the venlarged ends of the arms thereof will slide into the recesses 19-19 provided on the head, thus coperatively engaging the ders of the yoke proper and the head. lVhen thus assembled, it is apparent that the yoke proper and head will also move in unison in both buil' and draft.

From the preceding description, it will be seen that the parts may be readily assembled and disassembled and the draw bar and head B can be disconnected from the yoke proper by merely lowering the draw bar and head without disturbing the yoke proper, the latter being usually supported in gu1de- Ways' provided in the stop castings used with a gear employing a horizontal yoke, It will also be noted that the construction is such that the draw bar can be' employed to actuate a horizontal yoke ofthe tandem type although the yoke ing is of 'the single or'J twirnspring type. Furthermore, when the yoke proper and head B are assembled, it is apparent that the enlargements on the ends of the'yoke proper arms effectively serve to retain the vertical shoulf :soA

shown im the drawdraw bar butt in central position with regaging shoulders so arranged that the'head and yoke proper are assembled by relative vertical movement, the head being also provided with transversely extending shoulders adapted to eoperate with the usual shoulion horizontal. planes when in operative posi-l the free endsl of said U-shaped yoke tion,

being shouldered for detachably enproper gaging coperating shoulders on saidfhead,

, said'head having integrally formed means thereon adapted for engagement with cooperating means on afdravv bar for detachi f ably connecting the head to a draw bar.V

f3. As an article of manufacture, a yoke `f or railway draft riggings, said yoke comprising` anu-shaped yoke proper and a U- 'shaped healysaid head and yoke proper' having detachable shouldered engagement, said head having also transversely extendingpshoulders arranged to det-achably engage the shoulders of' a standard draw bar. 4. As an article of manufacture, a yoke for railway draft riggings,'comprising, a horizontally disposed U-shaped yoke proper, each ofthe arms thereof being provided at its free end with vertically extending shoulders, and a head ing recesses forming shoulders within which the shouldered portions of the yoke proper arms are engaged, said head having also transversely extending shoulders adapted to cooperate with the usual shoulders of a standard draw bar butt. Y

5. In a device of thecharacler described, the combination with a draw bar havingI a shouldered butt, of a head,.said head having upper and lower forwardly extended arms each provided with a transverse shoulder on its inner face whereby the head is assembled with the draw bar butt by relative transverse movement, and a yoke proper, the latter having vertically extending shoulders provided at the forward ends of the having vertically extend- I arms thereof, the head having correspondingly shaped recesses whereby the yoke proper is assembled with the head by rela-` tive vertical movement, the forward ends of the yoke proper arms being adapted to retain the draw bar in central lposition with respect to the head after the parts are asl sembled.

In witness that l claim the foreging I have hereunto subscrihedf my'name this 15th day of Feb. 1917.
